What does "improper lane usage" refer to?

Improper lane usage refers to the failure to adhere to the established lane markings indicative of where vehicles are permitted to travel. This concept encompasses a variety of actions, such as weaving in and out of lanes, straddling lane lines, or driving in a lane designated for a specific purpose (like a turning lane) without appropriate justification. When drivers do not follow these markings correctly, it can lead to confusion, disrupt traffic flow, and increase the risk of accidents.

In this context, while driving too slowly, not signaling, or overtaking in a valid lane can be problematic in their own right, these actions do not specifically refer to the misuse of lane markings. Thus, the focus is on the need for drivers to adhere closely to lane boundaries and the regulations indicated by road signs and markings for safe and effective traffic management.
